Our integral HWDP is made from one piece of AISI 4145H solid bar, fully heat treated,
all physical properties conform to API Spec 7 latest edition.
Our integral HWDP can easily solve problems arising in vertical holes in soft formation
by replacing part of the drill collars. The advantages include:

1). Reduced torque in high-rpm, deep drilling.

2). Less trip time as compared to handling a long string of drill collars.
